•Least Precise •Accuracy of 1/16” (.0625”)

•Used on large items and “non-precision” work

•Available in various lengths

Page 7: Why do we use measuring tools? What tools will we use? How do we read measuring tools? Where are these tools used in industry?

•Divided into increments of 1/16”(standard) *sometimes smaller

•Metric on the opposite side•Bold numbers indicate inches

Page 8: Why do we use measuring tools? What tools will we use? How do we read measuring tools? Where are these tools used in industry?

•Accuracy of .001” •0” – 6” , 0” – 12” , 0” – 36”

•Used on precision jobs

•Measures Outside Diameters, Inside Diameters,And Depths

•Each increment on the bar represents .100”

•Each round on the dial equals .100” or .200”Depending on the brand of the tool

•Bold numbers on the dial represent .010”

•Small dashes equal .001”

Page 12: Why do we use measuring tools? What tools will we use? How do we read measuring tools? Where are these tools used in industry?

•Most accurate •Accuracy of .0001”

•Available in various sizes, from 0” – 1” up to 35” – 36”

•Used to measure Outside Diameters
